Allow Page Access only to the Logged in Users

• It's common across many sites that you allow certain pages of your site only to the logged in users.
• Here, I am providing a simple way to do that in your site
• The main idea is, when users' credentials are verified, we store the information in the session object. Later, if a restricted page is being accessed, we check if the user is a verified/(logged in) user, if so we allow him access otherwise not
• You can use individual session variables to store some information about the user and logged in status. However, that may not be a great way. Better, to use an object to store user information and login status information. Then throw that object to the session variable.
• You will need to use this object (session variable) across your site in all restricted pages; hence, using global variables concept may help.
• Here, I will present code that will show you 1. a class to store user information 2. global variables class implementing the method to check if any user is logged in [from anywhere in your application] 3. a login form that will create a user object to store user information upon successful login and throw that object in session 4. a test restricted page that will check if any user is logged - if yes, go forward else redirect the user to the login page
• The class for storing user information is as below. You can keep the class in the App_Code folder
• Now the Global Variables Class. You can keep the class in the App_Code folder
• Now the login form (frontend) code
• Now the login form backend code. Check the method that checks for login credentials and create the loggedinuser object
• The test page that will restrict access for not logged in users.
